Searched around a bit and haven't been able to locate anything with a solution to my specific problem. I've been rebuilding a 1998 coupe for about a year now and I've discovered very recently that when I'm trying to move the driver side mirror with the power mirror switch it makes my door lock on the driver side make a weird noise but doesn't move the lock; also the mirror doesnt move. When I set the switch to the passenger side, the mirror moves correctly and nothing happens with the locks. Regardless of the position of the mirror switch, the lock switch on the driver door locks and unlocks both sides fine. Is there maybe a broken/crossed wire somewhere? My power windows don't work either but I assume thats a different circuit.

 

Carefully inspect the wires in connector C556 (driver's door jamb).

 

Does anyone have the correct wiring schematic? I have since solved my window problem, which seems to have originated from the c556 plug

 

For what?

 

For the driver side door harness plug. The C556

 

Do you have the service manual?

pg 202-21

 

Thank you

 

After cafefully inspecting the wiring diagram for C556, I discovered that terminal 15 and terminal 21 change functions for different model years.

For model year '96-'97
terminal 15 is a BLU/BLK wire for power mirrors
terminal 21 is a BLU/YEL wire for power door locks

For model year '98 and '99-'00 without keyless
terminal 15 is a BLU/YEL wire for door locks
terminal 21 is a BLU/BLK wire for power mirrors.

When I bought the car the driver side door was replaced, so its apparent to me now that the door was replaced with one from a '96 or '97 coupe.

 

Solved?

 

De-pinned and switched the wires and it solved the problem!
